Y = 180 - 52 - 59 = 69 degrees . . . . . . . . (angles on a straight line are supplementary, i.e. add up to 180 degrees)
x = 180 - 69 - 63 = 48 degrees . . . . . . . . (sum of interior angles of a triangle is 180 degrees)
Therefore, m/_x = 48 degrees.

Step-by-step explanation:
From the question we are told that:
Center of hyperbola at ( 6 , 9 )
Focus of hyperbola at ( 11 , 9 )
Vertex of hyperbola at ( 9 , 9)
Equation of hyperbola 
Generally the C and D of the hyperbola equation is mathematically given by



Generally the A and B a of the hyperbola equation is mathematically given by






Therefore with Center,Focus ,Vertex on the same line
